Brief Summary:
Corneal refractive surgery is an effective way to correct refractive error. Modern corneal refractive surgery for the correction of myopia or hyperopia can achieve or close to the expected goal, but to eliminate astigmatism is always one of the major problems of corneal refractive surgery. The key point in the correction of astigmatism is that as a vector parameter, astigmatism has both magnitude and direction. The angle error may be caused by the rotation of the patient's head position and the involuntary rotation of eyes. Phototherapeutic keratectomy can precisely cut the corneal tissue, and is often used in clinic to remove corneal scars or repair corneal surface morphology. In this study, the excimer laser therapeutic keratectomy mode was used to achieve accurate marking of the axis of astigmatism by setting the treatment laser parameters. With the help of the static cyclotorsion of the eye, the precise treatment of astigmatism could realize.
